In Trade Allowance Management, a Trade Allowance (Trade Promotion) can include a lump sum activity where we agree to pay our customer a sum of money for doing something for us, such as advertising our product on their website.  Legally, for tax purposes, a business must be able to accrue this expense.  We assume a liability for this expense as soon as the First performance date is hit.  So we owe the money and therefore we need to assume the liability even though we have not paid it yet.  Ideally, similar to how Rebate Program Ids allow us to setup flexible expense and accrual accounts, lump sum promotions desperately needs the same capability for accruals.  One accrual account is not enough - need to support the option for varying accrual accounts for different promotion programs.  Lack of this capability prevents a wider uptake of this feature or requires customers to customize it in this way due to the fact that this is missing core functionality.
